Release notes

Site Agent MCP now requires MCP Server 2.0.0-beta6, and Site Agent's own code no longer uses APIs that Drupal 12 deprecates. Changes since 1.0.0:

  • Require MCP Server 2.0.0-beta6. It runs every tool call, prompt and resource read in its own fiber, so Site Agent MCP's FiberGuard wrapper is removed.
  • Fix Drupal 12 deprecations in Site Agent's own code: the native return types that core 12 adds to create() and the storage schema, commitOrRelease() for chat memory transactions, and toolsets saved without the trusted data flag.
  • The documentation uses the shared Drupal Pages theme and credits FivePaths.

On Drupal 12, chat turns still fail until Key 1.x supports attribute-based plugin discovery (#3484086).
